New compounds3band3xwere synthesized according to Scheme 3. The Williamson ether synthesis was applied top-bromophenol with 1,4-dibromobutane and α,α’-dibromoxylene, giving1band1x, respectively. Dibromides1band1xwere converted to bis(tert-butyl nitroxides),3band3x, by way of bishydroxylamines...
Herein, we report a straightforward way to access POXs through a cobaltヽatalyzed reductive polymerization. This method not only allows the direct preparation of electronically unmodified POXs, but also enables the copolymerization between o﹛ylylene dibromides bearing different aryl or benzylic ...
The carbon-halide bonds of o-xylylene dibromide and o-xylylene dichloride lie in planes perpendicular to the aromatic ring and on opposite sides of the latter.doi:10.1007/BF00928517B. A. ArbuzovI. M. KhamatullinaS. G. Vul'fsonA. N. Vereshchagin...
but also enables the copolymerization between o-xylylene dibromides bearing different aryl or benzylic substituents.The glass transition temperatures of the copolymers can be finely tuned by varying the ratio between comonomers.The obtained POXs are solvent processible and amenable for thin-film ...
